“…In fish, patterns of contraction required for swimming are coordinated by interneurons in the spinal cord, generating rhythmic, and alternating contractions on the left-and-right side of the body (e.g. Uematsu, 2008;McLean and Fetcho, 2009;Fetcho and McLean, 2010). External electrical stimulation by electrofishing interferes with normal functioning by inducing action potentials in neurons and/or muscle fibres.…”

“…These side effects result from simultaneous electrically induced muscle contractions at both sides of the fish' body, an unnatural response because mutual inhibition via interneurons in the spinal cord normally prevents simultaneous contractions of left-andright swimming muscles in fish (e.g. Uematsu, 2008;Fetcho and McLean, 2010) and mainly occurs in fusiform fish with a high number of small vertebrae such as trout and salmon species (Snyder, 2003) or Atlantic cod (Soetaert et al, 2018).…”

Electricity can be used to facilitate fish and invertebrate capture in both marine and freshwater environments. In freshwaters, electrofishing is largely used for research or management purposes. In marine environments electrofishing is principally used in the form of electrotrawling for the commercial capture of fishes and benthic invertebrates, in particular common sole (Solea solea L.), brown shrimp (Crangon crangon L.), and razor clams (Ensis spp.). The terminology and definitions used to describe the electrical stimulus characteristics and experimental set-ups have, so far, been diverse and incomplete, hampering constructive discussion and comparison of electrofishing studies. This paper aims to (i) harmonize existing terminology, abbreviations, and symbols, (ii) offer best practice recommendations for publishing results, and (iii) provide a concise and comprehensible reference work for people unfamiliar with this topic. By incorporating common practice in marine electric pulse trawling terminology and related freshwater electrofishing studies, based on existing terms where possible, we provide a framework for future studies. The suggested guideline is recommended by the ICES Working Group on Electrical Trawling as a constructive approach to improved communication standards in electrofishing and electrical pulse stimulation research and publications.

“…An excision of the corpus cerebelli in Carassius resulted in movement disorder, frequent eye movement, and uncoordinated movement of paired fins (Tuge 1934). In contrast, some recent studies suggested that lesions of the cerebellum do not show severe motor defects (Roberts et al 1992;Matsumoto et al 2007a;Uematsu 2008). It was reported that rainbow trout in which the corpus was ablated were unable to maintain a steady position and were swept backwards by a rapid water flow.…”

The teleost fish includes largest number of species in the vertebrates. The basic structure of the central nervous systems, including the cerebellum, is conserved in teleost. The cerebellum of teleost fish is subdivided into three parts: the corpus cerebelli, valvula cerebelli, and vestibulolateral lobe (including the eminentia granuralis and lobus caudalis). Although anatomical features, including layer structure and cellular organization, of the teleost cerebellum are shared with those of other vertebrates, there are some exceptions. One of them is that the structure corresponding to the deep cerebellar nuclei is absent in the teleost cerebellum. Instead, the teleost cerebellar efferent neurons do not make clusters and are distributed within the ganglionic layer, which is equivalent to the Purkinje cell layer of other vertebrates. These efferent neurons use excitatory neurotransmitter and project their axons to other brain regions. According to this character, it could be said that the teleost cerebellar efferent neurons are functionally analogue to the neurons of the deep cerebellar nuclei. However, they have dendrites extending to the molecular layer like the Purkinje cells indicating that they

“…This muscle cramp is known in both freshwater electrofishing and marine electrotrawling to potentially cause internal injuries such as fractures and dislocations of the vertebral column, which may be accompanied by haemorrhages . These side effects result from simultaneous electrically-induced muscle contractions at both sides of the fish' body, an unnatural response because mutual inhibition via interneurons in the spinal cord normally prevents simultaneous contractions of left-and-right swimming muscles in fish (e.g., Uematsu, 2008;Fetcho and McLean, 2010) and mainly occurs in fusiform fish with a high number of small vertebrae such as trout and salmon species or Atlantic cod .…”

Effects of electrical stimulation on marine organisms

According to de , the likely earliest record of thinking about applying electricity to capture marine organisms was in 1765 by Job Baster when he wrote (in old Dutch): "Zoude nu de electriciteit, wier schokken zoo veel overeenkomst heeft met die de sidderaal veroorzaakt, op de garnaat (garnaal) geen uitwerking doen? My dunkt, het is waardig, zulks te onderzoeken. " (translation to modern English: "Would electricity, which shocks are so similar to those produced by the electric eel, have no effects on shrimp? In my opinion, it would be worthwhile to investigate this. ") A more concrete development by Isham Baggs in 1863 was patenting the idea to use electricity from batteries for, amongst others, the capture of fish (Baggs, 1863). It was not until the 20th century, however, that attention shifted to investigate the physiology and behaviour of marine organisms in response to electrical stimulation in shrimps but also echinoderms, flatfish, round fish, and whales (
